  • Abstract:
  • Real-Time operating conditions of digital integrated circuits play a key role in state-of-the-art systems. The overhead resulting from margining for worst case conditions is now a major energy contributor. In this paper a timing error tolerant circuit technique for low- power timing- error control is proposed. Controlling the transparent window of the clock enables the critical path to detect and correct the timing error-induced irregular data transition that occurs after the clock's rising edge. The timing error is directly corrected by a small amount of logic. It also introduces a time borrowing strategy, which corrects for future errors. The time-borrowing technique can be used at any site that has a quick flip-flop setup time. The timing error occurs in two stages sequentially, the arranged CLK in the second stage keeps a transparent window open long enough to allow regular data to be saved without modifying the system CLK.
